to be lubricated, for instance, the bearings ot l a machine.

The conditions ot use ot such an apparav tus vary through a comparatively wide range. This includes the number ot points to be lubricated; the need or laclr of need of warming the oil; the character of the heating medium7 it such be used; the character and position of 'the surface or part from which the pumping apparatus is supported; the difrection in which the several liquid delivery pipes leadl; relative positions of the pumping apparatus and the pump driving shaft; the capacity of the oil storage reservoir, etc.

The main object of the present invention is to so construct the apparatus that it may be readily modified, adjusted or changed to suit the particular conditions o'l use. rlhis object issecured by providing'a plurality ot separate elements, parts or sections adapted to be assembled to form the complete apparatus, said elements, parts or sections being so designed that they may bey assembled in a wide variety of different arrangements or combinations according to the wishes or needs ot the user.

As a further importantJ` feature the elements are so designed that they form the liq.- uid storage or supply receptacle and enclose all of the working parts. These diderent sections may serve for pumping, pump driving, heating, supporting, capacity increasing, etc. Any desired number ot the section of each particular kind may be employed in making up the complete apparatus. All of the units of certain kinds, such tor instance, as heating and capacity increasing may be omitted, it not needed.

In the accompanying drawings, I Ahave illustrated one embodiment of my invention. lt will be understood that this is merely for 176,393, and in Switzerland April 15, 1926.

Fig. 'E' is a transverse section on the line 7 7 et Fig. 2 showing the oil pipe connections.

The device as illustrated in Fig. 1 is made up ot a plurality ot sections or elements each having an annular wall and adapted when assembled to form an oil storage reservoir.. These sect-ions include end sections A and B; a driving or power section (l, a pair of supporting sections D, a plurality ot pumping sections E, a heating section F and a capacity increasing sectionGr. These all have cylindrical peripheral walls ot the same diameter and general character and so constructed that when the sections are placed end to end and clamped together they torni a substantially tluid tight liquid receptacle. of sections may be employed, it desired, and certain ot the hindso1 sections,'such for instance', as heating and capacity increasing may be omitted. ll` here may be any number ot the pumping sections.

Although, within the broad scope ot' my invention, l may provide any suitable `term ot' pumping mechanism within each pumping section E and adapted to be operated Other kinds g5 Cates with the interior of the reservoir.

from an axially disposed shaft, I preferably employ the type of mechanism illustrated in Figs. 1 and 2. The pumping element or section has a peripheral wall 2 which is provided at one point with a projection or boss serving as an oil pipe connection 8. Adjacent to this connection, the wall provides a cylindric surface 4 constituting the valve surface of the pump. Within the section there is provided a valve member 5 which is adapted to oseillate about a center eccentrieally disposed in respect to the axis of the section. The peripheral wall carries inward- 1y extending flanges or bracket parts 6 provided with cylindric surfaces concentric with the axis of oscillation of the valve 5 and serving to guide and position the latter and hold it against the valve surface 4. The peripheral wall 2 also carries brackets or a spider 7 which may carry the parts 6 and also serve as a bearing to hold the rotatable element of the ump concentric with the peripheral wall.

T 1e valve surface 4 of the peripheral wall has an oil suction passage 8 which communi- It also has an oil delivery passage 9 which communicates with a passage 10 in the oil pipe connection 3. The valve member 5 carries a piston 11 movable radially of the valve in a pump cylinder 15 which communicates alternately with the suction passage 8 of the delivery passage 9 as the valve 5 is oscillated.

The piston is operated by an eccentric disk or cam 12 mounted on a shaft or tie rod 13 and engaging a slidable member or cross head 14 connected to the piston 11 and movable radially in respect to the axis of oscillation of the valve. The eccentric 12 has lost motion connections with the slidable member or cross head 14 and acts to force the latter during the delivery stroke While springs 1G, mounted in the valve 5, engage the slidable member to torce the latter in the opposite direction and hold it against the eccentric 12. L Forlimiting the stroke of the piston 11, there is provided an adjustable stop in the path of the cross-head 14. This means is shown as an adjusting screw 17 extending through the peripheral wall 2 from the side opposite to the oil connection 3 and provided with a head 18 whereby the position of the adjusting screw may' be varied at will. This head or handle 18 is provided With a pointer or indicating mark which is movable over av scale on a supporting or guiding boss on the peripheral wall so that the operator regulate the stroke of the piston and the quantity of oil which is sucked in at each suction stroke and conducted to the point to be lubricated.

In the operation of the pumping element, the eccentric l2 is rotated by means hereinafter described and acts to not only force down the piston and permit its upward movement by the spring 1G, but also acts to oscillate the valve 5 so that during the suction stroke of the piston, the cylinder 15 is in communication with the suction passage 8 and during forcing stroke it is in communication with the delivery passage 9. The down stroke is a positive one so that the oil is forced out under pressure, but the suction, stroke is due to the springs and may be limited by the stop 17. Therefore it is not essential that the cylinder 15 be in communication with the suction passage 8 during the entire up stroke.

The shaft 13 is not necessarily rotatable. As shown it serves primarily as a connecting or tie bolt for holding the sections together in assembled relationship. The eccentric disk has a hub which is provided with clutch teeth at opposite ends so that the hub of each pump may interengage with the hub of an adjacent pump or 'with the hub of the driving gear. Thus power may be transmitted from one pumping element to the next and any desired number of the pumping elements may be assembled. with their eccentrics interlocked and the eccentric of the end of one such pumping element connected to the drive. The eccentric disks may be oriented so that they do not give their respective forcing strokes at the same time. Thus the torque on the drive may be distributed and maintained substantially constant, and the delivery pipes may lead from different points around the periphery of the apparatus.

For supporting the device and for attaching it to any surface irrespective of `whether the latter be, below, above, at the side of, or inclined, there are provided the supporting sections or elements D. Each of these includes a peripheral wall section 22, and a foot or bracket 23. These sections may be assembled with the foot below as shown in Figs. 1, 2, 3 and 5 'or in any other position, as for instance, above and inclined as shown in Fig. (i. I have illustrating only two of these supporting sections, but it will be evident that a larger number may be provided, if desired, and that they may be positioned at other places in the assembled device than that illustrated in Fig. 1.

In some cases, it is desired to heat the oil or other liquid in order to reduce its viscosity and facilitate its distribution. For this purpose, there may be employed a heating section F, shown in Figs. 1 and 4. This unit includes a peripheral wall 29 and a heating coil 30 arranged in a tube 31. The ends of the wire project through insulation in the peripheral wall, and connected to terminals which may be mounted in a housing and into which the lead wires extend.

The heating may be effected by the action ot' a fluid instead of by electricity. In Fig. 5 there is illustrated a heating unit having a peripheral wall 3T through which extend pipes 38 and 39. These are connected to the opposite ends of a pipe or coil 40 so that hot air, hot gases, steam or other heating Huid may be circulated through the pipe to heat the liquid in the storage space. Either form of heating section may be rotated to bring the connections for the Wires or pipes to the most convenient point on the periphery of the apparatus.

For driving the pump there is provided a driving element C. This has bearings for a shaft 41 which may carry a gear, such for instance, as a Worm 42 meshing with a gear such as a Worm Wheel 43 encircling the shaft 13. The Worm wheel is mounted on, or is secured to, a rotatable sleeve 44 which may have vone end thereof provided with clutch teeth for meshing With the hub of the eccentric disk 12 of one of the pumping elements. The peripheral Wall 46 of this unit carries oil tight bearings for the shaft 41 and in assembling the parts of the device, the shaft may be caused to project in any desired direction and from either side of the apparatus. In Fig. 3 I have shown it horizontally disposed and in Fig. 5 I have shown it extending vertically'.

The ends of the apparatus may be closed by suitable elements, such as the caps A and B. These provide means for supporting the shaft or tie bolt 13 and comprising end Walls 25 and 2G as Well as flanges constituting portions of the peripheral wall ofthe apparatus.

n The bolt 13 serves to tie the entire apparatus together and at its ends may be provided with nuts or heads 47. One of the end elements, for instance, theelement B may be provided With a filling opening 48. 1

There may be as many of the oil delivery pipes as there are of the pumping elements. The several pumping elements may be rotated so that these pipes are attached lat diierent points around the. periphery oi the apparatus. The attaching means is preferably such that the pipes may be readily disconnected, if desired. As shown, partielllarly in Fig. 7, each pipe G() has a yoke or strap G1` which may extend around the oil pipe connecting port 3 and is provided With a head 63 which may be forced into the end of the oil passage 10 by the action of a clamping screw 62 Which may also have a head 64 for closing the other end of the oil passage 10. Thus the oil pipe may be readily connected to either end of the oilpassagef10 as the heads 63 and 64 may be similar.

To increase the storage capacity of the apparatus there may be provided sections G each of which includes merely a peripheral Wall GG. As many of these sections may be employed as desired.

In assembling the apparatus, the user may take as lnany of the dilerentsections as he desires and connect them together in any de' sections may be formed in any desired manner to provide liquid tight joints between the sections and to permit any section to be ro tated when the tie bolt is loosened. As shown each joint includes a flange 50 for entering a groove 51 of the next section. v
